Saving Flashcards and Notes in Other Formats Such as JPGS Or PDFS

Edit Subject

Other Offline Methods Such as PDFs of Notes/Note Cards (the back could be on the next pdf page) Or Save As JPGS or perhaps as a book file foor book readers would be good? I know I could Use the JPGs on my PSP and have them on the go.
Would be best if front back were saved as diffrent JPG Files so You could Flip to the next JPG and it would be thte card back.
